Karyotypes are described in Hemiechinus auritus and Paraechinus aethiopicus which have 48 chromosomes in 2n. The male complement of H. auritus consists of 43 macro- and 5 micro-chromosomes while that of the female comprises 44 macro- and 4-micro-chromosomes. The X chromosome is the smallest metacentric macro-chromosome, while the Y is a small subtelocentric micro-chromosome. These associate end-to-end at meiosis I.The male karyotype of P. aethiopicus consists of 44 macro- and 4 micro-chromosomes. The autosomes are metacentrics or submetacentrics in morphology. The sex-complex is characterized by the medium-sized X chromosome and the mediumsized submetacentric Y.
